What should you know about kojic acid for under eyes?

Dark circles do not have one cause. They may reflect pigment, visible blood vessels, shadow from hollowness, swelling, rubbing or inherited anatomy. Kojic acid can affect melanin production, so it may be relevant to pigment-related darkness, but it will not correct a hollow or vascular shadow.

The skin around the eyes is thinner than many other facial areas and has less room for irritation. A product intended for the cheek is not automatically suitable for the eyelids or lash line. [Kojic Acid](/materials/kojic-acid/) may be discussed as part of a broader plan, but placement matters.

Do not apply kojic acid to the eyelids, lash line or inner corners unless a qualified clinician has specifically advised it. If a product is intended for the under-eye area, follow its directions exactly, use a very small amount and keep it away from the eye surface.

Avoid rubbing, fragranced products and several active ingredients around the same area. Moisturise with a bland eye-area product and use sun protection that does not sting. A clinician can assess the type of darkness and discuss options such as [Skin Brightening Treatment](/treatments/aesthetic-procedures/skin-brightening-treatment/).

Rinse the eye with clean water if product enters it. Seek prompt medical care for persistent pain, marked redness, swelling, blurred vision, light sensitivity or a chemical-burn sensation. Stop use for eyelid swelling, blistering or a rash that does not settle.

Ask what is causing the darkness, whether the product is appropriate for the exact area, where it may be applied safely and what to use if the skin becomes irritated.
